Bug 1493659 - Part 2. Use buttonRef not the created reference function. r=birtles a=pascalc
This patch uses the buttonRef since the beta repository doesn't contain the
changes of bug 1494162. So we remove this created reference function.

Bug 1495055 - Accept layout viewport updates from the main thread right away on Android. r=kats a=pascalc
Usually APZ waits at least one transaction from the time the composition
bounds (visual viewport) is updated, before updating the (layout) viewport,
but this causes problems due to the visual and layout viewport being out of
sync during orientation changes and dynamic toolbar transitions on Android.

Bug 1490119 - Bump timeout for automationrelevance. r=tomprince a=release
Bump the timeout for pulling the automationrelevance json. For very large merges, this can take awhile. For example, https://hg.mozilla.org/projects/birch/json-automationrelevance/7ecef4cf1884534b0ba6271c9f94902b3ed644a6 takes ~22 seconds.
